Erich Würdemann (15 January 1914 – 14 July 1943) was a German submarine commander in World War II and recipient of the Knight's Cross of the Iron Cross of Nazi Germany.
In April 1933, Würdemann joined the Reichsmarine, which became the Kriegsmarine two years later. During the first year of the war he served on the destroyer Paul Jacobi, before transferring to the U-boat force in November 1940. After the usual training he served for one patrol aboard under Wolfgang Lüth, before commissioning the Type IXC U-boat in September 1941. He sailed on 5 war patrols, sank 15 merchant ships for a total of and damaged 3 ships of a combined .[1]
Würdemann's most successful patrol (his second) took him into the Gulf of Mexico in May 1942, where he sank nine ships and damaged three.[2] His next patrol took him to the waters off West Africa, where he sank another five ships and was involved in the Laconia incident.[1] After U-156 sank the passenger liner, which was carrying 450 British and Polish soldiers and about 1,800 Italian prisoners of war, the U-boat commenced rescue operations, and was joined by others in the area, including U-506; but the U-boats were later attacked by an American aircraft, which resulted in Admiral Dönitz issuing an order to the Navy not to pick up survivors.
Würdemann sailed to the waters off South Africa in early 1943 and sank two more ships.[1] Finally, on 14 July 1943, six days into his fifth patrol, Würdemann was killed, along with all but six of his crew, when U-506 was sunk in the Atlantic west of Vigo, Spain by depth charges dropped from a Consolidated B-24 Liberator of the United States Army Air Forces' 1st Antisubmarine Squadron.[3]
